SANITARY VENTILATING WATER-CLOSET BOWL.

Specification of Letters Patent.

Patented Apr. 2, 1918.

Application filed November 9, 1917. Serial No. 201,096.

specified, embodying an annular air chamher encircling the mouth of the bowl and in communication with the interior thereof, said chamber being adapted to be connected to a flue in which a natural 0 artificial draft exists, whereby toremove foul odors from the bowl and to thoroughly ventilate the same.

Anotherobject of the invention is to provide a water closet bowl having the characteristics above named, and which will be also effective to ventilate the toilet room by withdrawing the air therefrom, through the'water closet bowl in the manner above set forth.

A still further object of the invention is to provide a water closet bowl having the characteristics above described and which is simple in construction, thoroughly efficient in operation, calculated to interfere in no manner with the discharge of water, into or out of the bowl, and which may be installed at a low cost.

addition to the foregoing, this invention compreheuds improvements in the details of construction and arrangements of parts, to be hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings, in which similar and corresponding parts are designated by the same characters of reference throughout the several views in which the y appear:

Figure 1 is a view in vertical section of a water closet bowl, constructed in accordance with-my invention, and

Fig. 2 is a view thereof in plan. 7

With reference to the drawings, 1O indicates generally a water closet bowl of conventional form, having a discharge conduit 11 leading from the rear portion thereof as indicated. The front wall 12 is curved down to the base 13 as at 14. The edge of the mouth of the bowl is enlarged to form an inner roll 15 which is formed with a plural ity of apertures 16 directed into the bowl and communicating with the interior of the roll, the same being hollow. A water slipin the roll to supply water thereto which issues through the perforations and serves to flush the bowl. a

The inner roll is housed within a casing 18, which, in cross section, surrounds the inner roll for more than onehalf its circumference, the perforations l6 bein exposed.

The casing surrounds the top e go of the bowl and thereby forms in effect an outer roll. As will be noted the outer casing is disposed in spaced relation to the inner roll and is held in such relation by means of integrally formed studs 19 which are arranged around the bowl in uniform spaced relation as shown.

ply pipe 17 is connected to the channel with- A. wall 20 is provided in spaced relation to the walls of the bowl and base thereof, said wall, at the front of the bowl extending,

fromthe upper ed e thereof to the base. At the rear of the owl, however, the wall 20 extends from the upper edge of the bowl downward only a short distance. In this manner an annular around the bowl, communicating at all points with the space between the inner and outer rolls, and tapering downward, from the rear of the bowl to the base where the space 21 communicates with a circular opening 22 therein.

channel 21 extends When the bowl is installed, the opening 22 in the base is connected to a pipe 23 which communicates with the flue 24.- which extends through the building and opens above the roof, thus providing a vertical column in which a natural draft is createdand continues at all times. If desired, however, an artificial or forced draft may be induced in the flue.

In any event, foul odors from within the bowl are constantly drawn out through the flue, being taken from the bowl through the channel surrounding the inner roll and through The space between the front wall of the bowl and the wall 20. i

It will be obvious, that if the b1 .3. is installed in a toilet or bath room the air there-' with fresh air, without the use of any ventilating system.

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein maybe made. I therefore reserve the right and privilege of chan ing the form of the details of construction, or otherwise altering the arrangement of the correlated parts, without departing from the spirit of the invention or the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by LettersPatent is:

1. The combination with a water closet bowl, of a hollow perforated roll at the upper end thereof, a wall arranged in spaced relation to the bowl and exteriorly 01": the same, an annular inwardly directed transversely curved flange formed at the upper end of the wall and overlying" the roll to protect the same.

2. The combination. with a water closet bowl, of hollow perforated. roll the upper end thereof, a wall arranged in spaced relation to the bowl and exteriorly of the same, an inwardly directed annular flange formed at the upper end of the wall and overlying the roll to protect the same, and studs interposed between the roll and flange.

3. In a water closet bowl, the combination of a hollow annular roll forming the upper edge of the bowl and partly encircling the roll transversely and in spaced relation to form air chamber, the roll being perfo rated to discharge water into the bowl through the chamber, and a wall formed in spaced relation to the wall or" the bowl to define a passage which tapers downwardly and forwardly and is in communication at its large-end with the chamber and at its small end with an opening to be connected to a flue, whereby, to ventilate the bowl.

In testimony whereof affix my signature in the presence of two witnesses.
